A proper Scrub tool is desperately need in WLE (maybe in WL aswell).
What is falsely labeled as Playback Scrubbing in the manual, has nothing whatsoever to do with scrubbing. Scrubbing means playing backwards and forwards at a user-defined speed. What the WaveLab calls Scrubbing is actually Playback Restart! Take a look at Cubase’s Scrub Tool for a lesson in how scrubbing works.
It’s amazing that such a basic feature has been left out of WLE.
